Based on about 5-8 jumps on a Storm 170. Previous experience about 200 jumps on a Sabre 1 - 190 and about 5-8 on a Sabre 2- 170. I tried both the Sabre 2 and the Storm the same week. Conditions ranged from windy and turbulent to calm with no wind. My windloading was perfect as the storm cut through thermals and turbulence beautifully (the main reason I was downsizing). Turns were very crisp with no hesitation, perhaps not as forgiving for a student but it really followed my input. Flat turns were, well, flat. I didn't try a full brake turn, half brake turns were very quick! Front risers in general were tough to pull with lots of pressure in both level and turns. Not too difficult, just tough. Rear risers were sweet for slowing, flaring or turns. Full speed straight and level flight semmed faster than the Sabre 2 and much steeper. Partial brakes leveled out the canopy and really offered comparable (Sabre 2) glide distance. A long spot would have you in partial brakes a long time but brake pressure was not unreasonable and glide was much shallower. Slow flight somewhere around half brakes was not mushy but maintained good cell pressure and felt fully controlled. Openings were actually faster than I expected but without the shaking and sometimes whomping I get from the Sabre 1. Openings seemed to be on heading for both my packjobs and packs by the pros...No tendency for end-cell closure which I did see on the Sabre 2 (to be fair, it didn't affect the openings on the Sabre 2 anyways). What did affect openings was body position, any reasonable change in the harness as the canopy was inflating affected heading. I like this as you can actually steer the thing as it's opening. Unstowing the brakes/collapsing the slider! What a suprise, reaching up for the toggles/collapse cords has to be done at the same time otherwise I was able to turn the canopy easily just by shifting body position. My Sabre 1 has a single cord to collapse the slider so I reach up with one hand while steering with both toggles in the other. Bad habit! On the Storm I had to collapse the slider with two hands then unstow the brakes. There is so much extra brake line stowed that the canopy really picks up speed as you release the brakes. I'd hate to inadvertently release one brake early! Not bad, just different. Now for the amazing part. FLARE!!! I flared early, I flared late, I flared twice, I think I even forgot to flare until it was too late. I swear this canopy actually went upwards when I pulled my stoppin ropes! The steep approach took some getting used to but once you decide to brake, there is so much energy left in the canopy to flare, it does just that. Flare slowly from too high, it keeps flying. Flare hard from too low, it keeps flying. Flare too high, goof and let up, pull again lower, it keeps flying. Even on no wind landings and higher wingloading (for me) the Storm levels out beautifully during flare, holds for a second or two, and let me down gently (all but one time, but that was my fault, and the grass stains are coming out just fine thanks.) My overall impression is that the Sabre 2-170 is a sweet stable canopy. The Storm-170 is a sports car that even I can handle! Last year my instructors suggested that I downsize to the Sabre 2. I don't think they had tried the Storm when they made that recommendation.
